At 9:30 tonight, Bai Yansong hosted the live broadcast of "new coronavirus pneumonia" on CCTV news channel (channel 13), inviting academician Zhong Nanshan to introduce the epidemic situation.
It has been named sari, and it is determined to be the evolutionary virus of SARS, with the same pathogenic mechanism. After the virus enters the human body, it interferes with the immune system, making the immune system mistakenly think that the lung cells are foreign substances to attack. Patients are killed by their own immune system. At present, all the drugs on the market are ineffective. Only by the same way as SARS: suppress the immune system with hormones, but at the same time, the human body will be very vulnerable. At the same time, the virus is more intelligent than SARS: 1. The incubation period is longer; 2. The body temperature of some patients is always normal from infection to disease onset to death, that is to say, fever is not the characteristic symptom of the disease, and the complete screening cannot be ensured through body temperature screening, which is also the reason for the closure of the city. 3. The transmission speed is faster. At present, only evidence of air transmission is available, but it is not clear whether there are other ways. So, no party, no crowded place
